Method Details

transactionFinished

public void transactionFinished(TransactionEvent e,
BackgroundTaskStatusProviderSupportingExternalCall status)

Description copied from interface: TransactionListener

Called when a transaction has stopped.
The class TransactionHashMap merges duplicate AttributeEvents. In case the Attribute path for the same Attributable is not equal, detailed information about Attribute path is lost. Instead a generic AttributeEvent containing just the Attributable is in the list of changed Objects (see TransactionEvent).
In case no detailed information about an Attribute change is available, your code should completely re-process the affected Attributable.

Specified by:

transactionFinished in interface TransactionListener

Parameters:

e - the EdgeEvent detailing the changes.

transactionStarted

public void transactionStarted(TransactionEvent e)

Description copied from interface: TransactionListener

Called when a transaction has started.

Specified by:

transactionStarted in interface TransactionListener

Parameters:

e - the EdgeEvent detailing the changes.

postDirectedChanged

public void postDirectedChanged(EdgeEvent e)

Description copied from interface: EdgeListener

Called after the edge was set directed or undirected.

Specified by:

postDirectedChanged in interface EdgeListener

Parameters:

postSourceNodeChanged

public void postSourceNodeChanged(EdgeEvent e)
